BRIEF INTRODUCTION

This application requests a Patent of Invention for IMPROVEMENTS TO AJUICE EXTRACTION MACHINE, particularly an extremely compactcommercial-scale fruit juice extraction machine that is extremely easyto handle and transport, being noteworthy for the unusual configurationof its construction that, among other items, is fitted with aswing-lidded waste-bin at the front whose side walls are close to thepeeler cups when completely closed, allowing easy waste pith, pulp andpeel removal when open. This invention is also noteworthy for afruit-rack mounted on and connected to the mobile peeler that holds thefruit during the second stage (when the fruit is on the mobile peeler)with this rack being smooth-surfaced and slightly curved (with a broadradius), serving as a waiting stage before the fruit falls onto thepeelers, without damaging the fruit and ensuring that it slides easily,in addition to significantly enhancing the efficiency of the machine,which is small compared to others, although highly productive.

FIELD OF APPLICATION

Fruit juice extraction in the commercial sector.

STATE OF THE ART

Since 1995, the inventor has devoted time and attention to thedevelopment of fruit juice extractors, filing the first patentapplication N° PI9502244-9 for a commercial-scale machine with thefollowing characteristics: a machine developed for processing citrusfruit in general with no manual contact, comprised of a tubular chassisattached to an extraction compartment in which is installed a gearedmotor rotating a crankshaft that in turn axially revolves one peeler cupagainst another peeler cup in order to trap the fruit released by atrigger located at the outlet of a fruit tray, with one of theabove-mentioned peeler cups having a central shaft and the other a juiceextraction perforation pipe, whereby all these solid wastes aredischarged into a waste-bin while the liquid runs through a filter,flowing sequentially through a pipe in a horizontal “S” shape,

Within the line of research pursued by the inventor, the technology wasimproved and an application was filed under N° MU7501780-6 for themachine feeder system, describing the steady supply fed into the machinein a synchronized manner through a feeder arm positioned across thefeeder outlet, preventing the fruit from moving forward, with this armlifting as the mobile peeler cup moves towards the static (fixed) peelercup and allowing a fruit to fall from the container, and so onsuccessively, whereby a fruit falls directly on to the peelers in eachcycle.

Progressing with the state of the art, this inventor filed anapplication under N° MU7502884-4, whose purpose was to improve thefeeder system even more through introducing a fruit stirrer on the toptray and a new dispensing device fitted with a spiral spring placedacross the feeder outlet, allowing only one fruit to fall each time.

Analyzing the indicated state of the art for the line of progressiondeveloped by this inventor, the first issue to be addressed with regardto PI9502244-9 is the shape and placement of the waste-bin, as with theprevious technique it is located very far away from where the extractionoccurs. Thus, bearing in mind that the fruit peel, pith and pulp areexpelled at random, in addition to the possibility that a piece of fruitmay “burst”, wastes stick to the sides of the machine under theseconditions until reaching the waste-bin. Consequently, in order toremove the wastes from the waste-bin, it is necessary to take it out ofthe machine. It is even harder to clean the walls surrounding thepeelers, especially the walls between such peelers and this waste-bin.

The second issue to be addressed consists of the so-called second stageof the fruit, which is when it is positioned over the mobile peeler, asthis consists of blades and its outer shape does not allow the fruit toslide easily during linear movement. In this context, another technicalissue noted by the inventor relates to the fruit wastes, which arethrown towards the top part of the machine, as the peeler is hollow.

THIS INVENTION

In order to resolve the issue of the distance of the waste-bin, theinventor designed a surrounding swing-lidded waste-bin that addressesnot only the distance factor but also its manner of construction. Inthis invention, the walls of the surrounding swing-lidded waste-bin areclose to the peelers which also means that, in addition to helpingresolve the wastes removal problem, the machine is very compact,although highly productive. On the other hand, the side walls of theabove-mentioned surrounding swing-lidded waste-bin are semicircular,whereby it can be rotated, thus allowing very easy waste removal.

With regard to the second aspect addressed, meaning the fruit slippingonto the mobile peeler, the inventor introduced a fruit-rack positionedon the outer top side of the mobile peeler, whose movements are linkedthereto. This means that the fruit lies on a more suitable smoothsurface, particularly as its curved shape has a radius far larger thanthat of the fruit itself, constituting a tubular structure that releasesthe fruit. This fruit-rack also serves to deflect wastes, not allowingthem to fly upwards and thus keeping the top part of the machine clean.

In other words, when compared to the mentioned documents constitutingthe state of the art, the most relevant innovations in this inventionare related to the parts of the machine arrayed after the dispenser orfeeder device, considering the characteristic operating cycle of thistype of juice extractor.

With this new machine, according to the invention, it may be said thatthe fruit runs through three stages, all synchronized by the mobilepeeler movements. In the first stage, the fruit lies on a cross springin the feeder; in the second stage, the fruit falls onto the fruit-rack,released by contact between the spring release devices resulting fromthe linear movement of the mobile peeler towards the fixed peeler, beingheld above the mobile peeler by the cross-spring; in the third stage,the fruit falls onto the fixed and mobile peelers, resulting in thefruit being peeled and the juice being extracted.

In more technical terms, this invention places a spiral cross-springbetween the feeder pipe and the fruit-rack sub-set that initially holdsthe fruit in the vertical feeder or dispenser (first stage), with thisspring activated through devices inserted in the above-mentionedfruit-rack sub-set that are triggered by the same axle that rotates themobile peeler, whereby the fruit waiting on the rounded fruit-rackconstitutes the second stage, whereby such fruit will be released on tothe peeler sub-set only when the fruit movement component on thefruit-rack sub-set touches such fruit during linear movement, allowingit to fall between the peelers for the third stage, which is the act ofpeeling the fruit and extracting the juice simultaneously. In otherwords, in an almost simultaneous operation, the spiral cross spring istouched by the spring activators, releasing the fruit lined up in thefeeder pipe, which then falls onto the above-mentioned fruit-rack.

Thus, the fruit running through the dispenser falls onto the top part ofthe mobile peeler and then on to the peeler during the next cycle, whenthe juice is extracted. Assuming that the dispenser or feeder pipe isfull, there will be one fruit at each of the stages in each cycle.

ADVANTAGES OF THE INVENTION

Among other advantages that are clear from the preceding description,the advantages rated as relevant to this invention may be listed asfollows:

-   More efficiently synchronized fruit feed as the fruit slips more    smoothly over the fruit-rack during the second feeder stage;-   Less damage to the fruit, due to the shape and polished surface of    the fruit-rack;-   Keeps the inside of the machine cleaner;-   Easier and more complete cleaning and removal of pith, pulp and    peel;-   Machine with a lighter, less complex and more compact structure,    requiring fewer parts with lower manufacturing costs.

The IMPROVEMENTS TO A JUICE EXTRACTION MACHINE addressed by thisapplication for a Patent of Invention are improvements to a juiceextraction machine (M), comprising a fruit-rack sub-set (1) with acurved cross-section whose movement is synchronized with the mobilepeeler rotating axle (2), with such fruit-rack (1) being attached to themobile peeler sub-set (2) through slots (3), with the machine includinga cross-spring (4) attached at the bottom of the feeder/dispenser pipe(5), with such cross-spring (4) having a means of activation (51)located on the fruit-rack sub-set (1); the improved machine (M)comprises a swing-lidded waste-bin (7) in front, with such swing-liddedwaste-bin (7) having substantially semi-circular sides (8) close to themobile (2) and fixed peelers (2B) that are aligned with each other, withthe latter being concatenate with the filter and piston sub-set (67)mounted inside the fixed peeler (2B) (FIGS. 6, 7 and 18).

In a preferred and compact construction, the machine (M) presents a flatand level support base (9) that is rectangular in the version presentedhere, whose bottom front part holds a drip tray (10), as well as flatvertical side-cowlings (11), rear vertical cowlings (12), top cowlings(13) that form a top front surface (14) holding the operating buttons ordisplays, one of which is an emergency button (15), a general switch(16), an on-switch (17), an off-switch (18), and LED indicator lights(19) for peels (19B) and open (FIGS. 1, 2 and 5).

Just above the surface (14) is a cowling (20) with a fruit funnel (21),fitted at the front with a sizer element (22) that controls the maximumand minimum sizes for fruit entering such funnel (21), consisting of awire element that communicates with the feeder/dispenser (5) in themachine, with this funnel having an inflow rim (23) and a cylindricalwire conduit (24) projecting into the machine at a slight slant that issufficient to allow the fruit to move forward through gravity. Theelectro-electronic part of the machine is a commonplace solution notaddressed by this protection, with the components listed forclarification purposes and allowing a person skilled in the matter toreproduce the product, with a market solution (FIGS. 1, 2, 3, 6, 18, 19,20 and 21).

The rear part of the top cowling (20) has a linking mechanism (25) thatmoves it into the open or closed position, as the inside consists of ametal structure made from rectangular sheeting sections (26) on thesides that are supported on the bottom metal frame (27) of the supportbase (9), with the latter holding the sheet metal sections (28), withthe rear sections (29) being pierced (30) in order to provide a means ofventilation for the gear-motor sub-set (31) that powers the mobilepeeler (2) and fruit-rack (1), while the front section is a solid metalsheet (32) with curved edges (33) attached to the sheet metal structure(26), such solid metal sheet (32) topped by a thin metal sheet withfront slots (34), above which are the pivot points (35) of theswing-lidded waste-bin (7) whose sides are approximately semicircular(8), with such waste-bin having a flange projecting from its transversalrim (36) with a spring-pin locking device (37) that keeps it latched inthe closed position, while the front metal sheet (38) is fitted with ahandle (39) made from plastic or some similar material (FIGS. 4, 5, 6,18, 19 and 23).

The front metal sheet (38) has a convex (inverted slant) surface wherebywhen the swing-lidded waste-bin (7) is in the open position, it forms asloping surface (40) that allows easier waste removal and cleaning(FIGS. 10, 17, 18 and 19).

In the rear part of the machine is the gear-motor sub-set (31), which isin turn attached to the sheet metal sections base affixed to thestructure (27) of the metal base (9) and the rectangular metal sheetsections structure (26), being held thereto by screws or otherconventional means of attachment (FIGS. 6 and 7).

Projecting from the top end of the gear-motor sub-set (31) is a crankarm (41) whose pivoting end (42) is connected to an axle (43) with apulley (45) that in turn runs through a guide (44) across the machine,with such guide (44) having grooves at the opposite ends to hold heopposing cylindrical axles (46) running through the metal sheet sideguides (47) and with the guide (44) supported on the front edges (47B)of the structural part of the machine, with such metal sheet side guides(47) having rectangular dips (48) where the spiral springs work (49)with plastic stoppers (50), whose extended linear movements are limitedby the rectangular dips (48), thus defining the maximum movement of theabove-mentioned plastic stoppers (50), through converting the rotatingmovement of the crank arm (41) into the linear movement of the guide(44). The opposing parallel axles (51) of the mobile peeler (2) areattached to the guide (44), with such opposing parallel axles (51) beingfully attached to the guide (44) and running through the structure ofthe machine on bushings (52) incorporated into the structural metalsheet (53), and with such opposing parallel axles (51) extending to theopposite sides of the mobile peeler (2), where they are attached to thediamond-shaped base (53B) in order to endow the latter with alternatinglinear to-and-fro movements (FIGS. 8, 9, 18 and 19).

This substantially diamond-shaped base (53B) has opposing vertices alongthe length of the diamond with holes (54) through which theabove-mentioned axles run (51); with such base providing the verticalhousings (55) that hold the slots (3) of the fruit-rack sub-set (1),with the latter comprising a base/support (56) with a concave curve (57)whose radius is larger than that of the fruit (F) that it will hold,with substantially “C”-shaped arms (58) projecting on both oppositesides from the rear part of such fruit-rack, with internal reinforcementelements (59) whose tips are fitted with substantially “U”-shapedsupports that hold axles with pulleys (60) activating the spiralcross-spring (4) that releases or holds the fruit (F) during theoperating stages of the machine (M) (FIGS. 11, 12, 13, 14 and 15).

When moved in a linear direction, the substantially “C”-shaped arms (58)with the pulleys (60), alongside the mobile peeler sub-set (2) reach thecross-spring (4) that runs through the axial cross-section (4B) of thefeeder/dispenser (5), with such cross-spring (4) supported by theparallel pulleys (61) attached to the sides of the machine casing,releasing the fruit (F) that drops by gravity on to the cradlebase/support (56); such cradle base/support (56) consists of a smoothsurface (62) with an elongated cross-section whose center (63) islowered slightly into a “V”-shape that forms a curve (57) preventingdamage to the fruit (F) and allowing it to slip down easily; on the toppart of the smooth surface (62) is a rounded cut-out (63B) whose linearmovement either holds the fruit back or releases it into the next stage(FIGS. 11, 20 and 21).

The filter (64) mounted on the front part of the machine (M)communicates with the inner part of the fixed peeler (2B) and the“S”-shaped pipe (65) in order to release liquid through the activationdevice (66). The filter and piston sub-set (67) is attached to themachine (M) by a cross-blade (68) affixed to the axles (46) byconventional means and with a front lid (69) that may be removed whennecessary (FIGS. 6, 18 and 19).

According to the invention, with this new machine (M) the fruit (F) runsthrough three stages, all synchronized by the movement of the mobilepeeler (2). In the first stage, the fruit (F) lies on a cross-spring (4)in the feeder/dispenser (5); in the second stage, the fruit (F) falls onto the fruit-rack (1) through the contact action in the activationdevice releasing the cross-spring (4) during the linear movement of themobile peeler (2) towards the fixed peeler (2B), being kept above themobile peeler (2) by the action of the cross-spring (4); in the thirdstage, the fruit (F) falls between the fixed (2B) and mobile peelers (2)that extract the juice. With each new cycle and with thefeeder/dispenser (5) full, one fruit (F) drops at each stage.

Most of the components used in the construction of the machine (M) aremetal, using stainless steels almost exclusively and conventionalmanufacturing means such as welds and screws, among others. The othernon-metal components are normally food-grade polymers, with the means ofprocessing being analogously compatible with market technologies.
